Drilling mud

Patent:

Abstract

Drilling mud is proposed which contains clay, water, water output reducer, pH regulator, viscosity reducer and hydrogen sulfide absorber. In order to improve the absorbing capacity of the drilling mud with pH 8-11 and simultaneously preservation of the technological properties of the mud, it contains as the absorber of hydrogen sulfide pyrite cinders with the following ratio of components, % by mass: clay 5.0-35.0; water output reducer 0.2-2.0; pH regulator 0.05-0.25; viscosity reducer 0.1-1.0; pyrite cinders 0.5-4.0; water--the rest.
